Patricia Gualinga stands serenely as chaos swirls about her. I find this petite woman with striking black and red face paint at the head of the People’s Climate March in New York City on September 21, 2014. She is adorned with earrings made of brilliant bird feathers and a thick necklace of yellow and blue beads. She has come here from Sarayaku, a community deep in the heart of the Amazon rainforest in Ecuador.

Behind Gualinga, 400,000 people are in the streets calling for global action to stop climate change. Beside her, celebrities Leonardo DiCaprio, Sting, and Mark Ruffalo prepare to lead the historic march alongside a group of indigenous leaders. Gualinga stands beneath a sign, “Keep the Oil in the Ground.” She has traveled across continents and cultures to deliver this message.

“Our ancestors and our spiritual leaders have been talking about climate change for a long time,” she tells me in Spanish above the din, flashing a soft smile as photographers crush around the celebrities. She motions to the throngs around her. “We are actually speaking the same language right now.”

A year earlier, I traveled to her village in the Ecuadorian Amazon to research the improbable story of a rainforest community of 1,200 Kichwa people that has successfully fended off oil companies and a government intent on exploiting their land for profit. How, I wondered, has Sarayaku been winning?

This is not the story most people know from Ecuador. Headlines have focused on northern Ecuador, where Chevron is fighting a landmark $9.5 billion judgment for dumping millions of gallons of toxic wastewater into rivers and leaving unlined pits of contaminated sludge that poisoned thousands of people.

Sarayaku lies in southern Ecuador, where the government is selling drilling rights to a vast swath of indigenous lands—except for Sarayaku. The community has become a beacon of hope to other indigenous groups and to global climate change activists as it mobilizes to stop a new round of oil exploration.

What I found in Sarayaku was not just a community defending its territory. I encountered a people who believe that their lifestyle, deeply connected to nature, holds promise for humans to save themselves from global warming and extinction. They are fighting back by advancing a counter-capitalist vision called sumak kawsay—Kichwa for “living well”—living in harmony with the natural world and insisting that nature has rights deserving of protection.
